Definitions

  • Roller blind device in particular for a sunroof system
  • the invention relates to a roller blind device with a windable roller blind, in particular for a sliding roof system according to the preamble of claim 1.
  • the coil spring is formed as a so-called constant force spring, which has a flat in cross-section spatial form in the wound state and in the developed state has a curved in cross-section, kink-resistant spatial form.
  • constant force springs used as coil springs increased
  • roller blind must be connected to the constant force spring by means of material-locking connection method, eg gluing or welding. Sewing or otherwise positively connecting the blind sheet with the constant force spring would require breakthroughs within the constant force spring, which would undesirably weaken them. In this respect, such connection methods are ruled out in such a roller blind device.
  • roller blind remains stretched in the extended state in its transverse direction.
  • a conventional sun blind device has the disadvantage that an expensive winding shaft with an internal torsion spring is required.
  • Such winding shafts are relatively expensive and complicated in their construction of many items.
  • known winding shafts have a considerable weight, which is less desirable in vehicle construction.
  • it may be due to material fatigue that the roller blind, especially along its longitudinal edge areas is not always a sufficient
  • Preload in the longitudinal direction has, so that a smooth sliding of the roller blind in the guide grooves is not always guaranteed. There is even the possibility that at insufficient tension of the longitudinal edges of the Roller blind in the guide rails, the restoring force of the winding shaft for a reliable retraction of the blinds is not sufficient.
  • a roller blind device with a continuous winding shaft in which the winding shaft is connected in the region of a free end of the winding shaft with a drive mechanism arranged outside the winding shaft.
  • the object of the invention is to provide a roller blind device, in particular for a sliding roof, which is easy to install and has a reduced weight compared to conventional roller blind devices. At the same time is to be achieved that in each operating position over the operating time, a reliable tension of the roller blind along the longitudinal edges is achieved.
  • Another object of the invention is to provide a rolling device with optimized, i. to provide smaller required space requirements.
  • Another object of the invention is to provide simple and proven manufacturing methods, e.g. To maintain the sewing of the roller blind with guide straps.
  • the roller blind device according to the invention has as a winding device at least two independently rotatably driven winding rollers.
  • a continuous winding shaft can be saved, resulting in a significant weight reduction.
  • separate bobbins are easily executable and structurally simple in terms of their rotatable storage feasible.
  • the winding rollers are arranged in the region of the longitudinal edges of the roller blind, so that the longitudinal edges of the roller blind are reliably taut in each operating position.
  • Figure 1 A perspective schematic diagram of the roller blind device according to the invention
  • FIG. 2 is a schematic diagram of a first embodiment of a winding roll of the roller blind device according to the invention
  • FIG. 3 shows a basic section sketch of a second embodiment of a winding roll of the roller blind device according to the invention.
  • Figure 1 shows a roller blind device 1 according to the invention with a roller blind 2 in a partially wound state.
  • Roller blind 2 has along its longitudinal extent rarium depending on a longitudinal edge 3 and a displaceable in an extension direction 4 free transverse edge 5. Opposite to the free transverse edge 5 is the roller blind 2 about a winding axis 6, a Rollowickel 7 forming, wound up. The winding axis 6 is an imaginary axis of rotation. At the free transverse edge 5 a Auszugsspriegel 5 is suitably arranged.
  • the guide strips 9 are strip-shaped and consist of a flexible material, for example of a textile, a woven fabric, a knitted fabric, of plastic or of metal.
  • the guide bands 9 are firmly connected to the blind sheet 2, for example sewn.
  • the guide bands 9 form along the longitudinal edges 3 of the
  • Roller blind 2 in cross-section of a guide profile, which is guided in corresponding guide rails 10.
  • the roller blind 2 is connected in the region of the guide belts 9 at the opposite end of the free transverse edge 5 with at least two winding rollers IIa, IIb, wherein the winding rollers IIa, IIb are rotatably supported about the winding axis 6 independently.
  • the longitudinal extension of the winding rollers IIa, IIb in the direction of the winding axis 6 is compared to the width of the roller blind 2 low, so that a free distance D between the winding rollers IIa, IIb is present.
  • the roller blind is preferably wound without a rigid means forming a winding core.
  • winding rollers IIa, IIb are mounted independently of each other about the winding axis 6 in a rotational direction 14 rotatably.
  • the winding rollers IIa, IIb are formed in their longitudinal extent such that the roller blind 2 can be wound up in the region of its longitudinal edges 3 together with the guide belts 9 on the respective outer surface 12a, 12b of the associated winding rollers IIa, IIb. So that the roller blind 7 by its own weight in a horizontal mounting position not may sag unacceptably far, it may be appropriate to provide a support means 13, on which the roller blind 7 can rest.
  • the support device 13 may be formed, for example, by a partial region of a roller blind housing or roller blind box which surrounds the roller blind 7.
  • Each winding roller IIa, IIb is also drivably coupled by means of a suitable drive means 15 in the direction of rotation 14, in particular in the winding 14a.

  • the roller blind 2 is fastened in the region of its longitudinal edges 3 together with the respective guide rail 9 assigned to the longitudinal edge 3 on the roller body 7. Outside the roller blind 2, adjacent to the longitudinal edge 3, the winding roller IIa, IIb is connected to the formed as a spiral spring 15 drive means. Following the roller body 17 on the outside, the winding roller IIa, IIb has a bearing journal 18, which is rotatably and axially fixedly mounted in a bearing bore 19 of the bearing element 16.
  • the use of a Spiral spring 15 on the type of a clockspring has the advantage that the bobbins IIa, IIb almost independently of a winding position over the entire winding area can be acted upon with almost constant torque. This has the advantage that the operator, regardless of the Rollo ein for moving the roller blind 2 can spend almost constant forces.
  • the winding rollers IIa, IIb are also formed as a roller body 17 ', wherein the roller body 17' has a bearing bore 20 with the winding axis 6 as a central axis and sits on a bearing pin 21 which stationary with respect to the bearing element 16 optionally this is formed, and is rotatably mounted in the direction of rotation 14.
  • each winding roller IIa, IIb is coupled to a respective coil spring 15 as a drive device and independent of an opposite second winding roller IIa, IIb of the roller blind device according to the invention is rotatably biased and driven.
  • Guide strips 9 themselves must have no spring properties to ensure a winding of the blind sheet 2.
  • the provisionssb section9 be formed of conventional materials, such as plastic, metal, textiles or woven or knitted fabric. This has the consequence that for fastening the guide belts 9 on the roller blind 2 proven connection techniques, in particular positive connection techniques, such as sewing remain applicable.
